Major MemoryManager overhaul:
> Added a new container, itemsToAdd, that adds items created with createDelayed(...) on cleanUp (useful for situations where an entity creates another entity during its own update, causing looping issues unless you copy the items vector beforehand)
> TDelContainer renamed to TModContainer
> Added adopt(...) methods, that take a heap-allocated (with new) object parameter, and put it in the main container.
Fixed strange crash (possible compiler bug?) on global vector<string> destructor
Const-correctness improvements
